Ιβ62200 - Patent Specification No. 96137043 Revision of the revised page of July 8, 100. IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to wireless communication, and more particularly to a communication system for a packet-based unit Communication device and its method. [Prior Art] When a wireless receiving station receives a data packet, the receiving station can receive a data packet by means of a Frame Check Sequence (FCS), such as a parity check code or a signal check code. After detecting the packet error. If the calculated frame check sequence conforms to the transmitted frame check sequence, the receiving station can receive the data packet, otherwise the receiving station will discard the packet. In this way, the receiving station can determine the integrity of the received data. Because of many factors, such as interference or burst noise, although there is a convolutional code to correct the error, the data packet can sometimes be corrupted. In general, the frame check sequence check does not start until the entire packet is received. It will only start after the signal processing and demodulation of the received packet is performed. However, this communication system process wastes a lot of power and the possibility of loss of packets.

Packet loss can occur in the state of a hidden node. For example, the receiving station STA A can receive the signal from the receiving station STA B and the Access Point AP, and the AP can only receive the signal of the receiving station STA A (hidden node problem). If the receiving station STA 0758-A32772 D.

Received the damaged data packet of the receiving station STAB when the donation is lost. In the case of the packet length of the error decoded data packet, the packet data will also be lost. For example, in the case of a wireless local area network, such as 匕 匕 八 八 八 八 八 , , , , , , , , , , , , , , , , , , 。 。 。 。 。 。 。 。 If the length of the error-decoded packet is longer than the correct packet length, the packet may be lost. For example, if the correct packet length is a deleted bit (group and the error decoded packet length is 6W bytes, the receiver will stop receiving the packet before the packet length reaches 65535 bytes. Because the correct packet length is the deleted byte , other transfer stations or pick-up points may follow in pure (10) bytes

Continue to transfer the packet. In this example, the data packet is lost due to the length of the error decoded packet. X ’ uses the power storage capacity of portable power storage, which is consistent with b and lc

Another issue is power consumption. Wireless devices such as cells (such as batteries) only have a limited need for efficient power management. The 1 a, IEEE 802 'lln packet format is indicative of a non-high throughput (ηοη-ΗΤ) mode, a high-throughput hybrid mode, and a high-throughput non-mixed mode (Greenfield) mode, respectively. Non-high throughput mode is a low throughput data format. High-throughput mixed mode and high-throughput Greenfield mode are used for multiple input, multiple output orthogonal multi-frequency division (Multiple Input, Multiple Output Orthogonal Frequency 0758-A32772TWF1 (20110525) 8 1362200 1 July 8th, August 8th Amendment Amendment to the patent specification of page 96137043

It is possible to determine whether or not the error is generated in the demodulated input signal, and when there is a possibility that an error occurs in the demodulated input signal, a selection is made to decide whether the component needs to be stopped and which components need to be stopped. If the above-mentioned possible error occurs in the above-mentioned demodulated input data, the baseband module 310 performs an error code check in units of packets after completely receiving the above data packet. • When a possible error occurs, the preamble detection module 312 controls the baseband analog group 310 to generate an error indication signal.

The patent of the 9613 purchase number is revised. Before the first S2 S404, the 'detectable detection module 312 performs the packet receiving and receiving debt measurement method' to determine whether the demodulated input data is sent to the control base frequency, 31 〇W, then the detector group is set. 312 can generate an error indication signal. Pre-detection method 妒, 醢: The energy of the frequency-input signal, the pre-derivation in the demodulation data, the noise interference in the two-week bait material, or the dimensionality characteristic. ^ & 66. In step S406, if the demodulated input data occurs, the pre-detection module 312 performs selection to determine whether the component is required and which components are to be stopped. If a possible error occurs ^ The lean processing method of Fig. 4 continues with step S4 〇 8 if step S402 is not continued. And the detection module 312 disables the appropriate component in the communication device for one cycle and generates an error indication signal (S414). Pre-detection 'Bay J mode, group 312 can make RF module 3〇〇, signal processor 3〇6 '

And the baseband module 31 is disabled until it reaches the end of the current f-packet to reduce power consumption. The pre-detection module 312 can also re-initiate the other packet reception of the detection unit 302, and disable the baseband module 3 ι until another data packet is detected to reduce the packet loss of the input data. In step S410, the communication device obtains a complete data packet from the radio frequency signal for generating demodulated input data, so that the baseband module 310 can perform the demodulation of the input data in units of packets of 0758- A32772TWFl(20110525) 14 Patent Specification No. 96130343 modifies this error code check to determine the correctness of the data (steps). In the case of a packet error, the error check can be checked in the order of the frame check (F-cutence, FCS). If the demodulated input data ^correct 'base frequency module 3U' will produce an error in step state 4 5 tiger. ^ In the knowledge processing method, the communication device receives the complete data and determines the correctness of the input data, and the RF processing, signal processing, demodulation, and fundamental frequency processing are continuously customized in the entire data packet/in the data packet. The consumption is higher than the method disclosed in Fig. 4. In the case of receiving packets, the method 4 is used. In order to continue or stop the communication device = or the eve component to make decisions, reduce power consumption and reduce the packet loss. The method can be selected from a plurality of detection methods (Pilot tones e ec call, (4) symbol _, and path value detection (4) gift, as shown in FIG. 85, respectively, in the embodiment of the present invention, the pre-detection and measurement method 5〇~8G The flow chart 'let's delete the G2.lla/b/g/n standard. 3: The second picture shows the flow chart of the pre-detection method in Figure 4, using the strong 3 method 5 〇 using the RF input signal Energy can produce false pre-determination, thereby reducing the loss of communication in a box of if or packet.

Data symbol. Correspondingly, the expected known pilot symbol or data symbol V is obtained by the calculation of the 汾 汾 』 , for example, the absolute distance 座 座 # 、 and the known 丨 丨 symbol Α, representing the received-produced W and The error value between the job and the light material. Whether = Γ / 7 () 6 'front (four) module 312 determines the distance value di = the threshold value of the distance stored in the register. If so, the preceding ^ ; , , and 312 continue to step S·, if otherwise, the step S704 is followed by the next error distance value. The S7G8 towel is located in the S7G8 towel. Because the error distance value di exceeds the distance critical value, the error miscellaneous value em^eQum may be destroyed due to the rim noise or interference. The set detection 312 then checks the error count value err 〇 rc 〇 um = the error threshold value, and if so, the error is generated in step S 712. If not, then return to step S 704 to make more errors. Distance is different. The error threshold can be stored in a register. The distance threshold and the wrong boundary value are set in the initial register. ^ Figure 8 shows another flow chart of the pre-detection method in Figure 4, using the communication of Figure 3. Method 8: Use the path value of the Viterbi stone (^hmetde) to perform a pre-form that may produce errors. When the Viterbi algorithm is used to decode the received signal, the resulting path value can be used to determine the quality of the connection. More precisely, the final stage of the material diameter is used to determine the quality of the connection. In an embodiment of the invention, the minimum path value yields a data packet optimal path # value. In general, the status of the #线线0758-A32772TWFK20110525) 1362200 ί- / Patent Specification No. 96137043 Revision of the revised page on July 8, 100. For better, each state of the last stage of the path value will be displayed very Big difference. For example, in the final phase of Viterbi decoding with 4 states, one has a final path value {15, 165, 185, 300} and the other has a final path value {100, 125, 115, 93}. The former has a better connection quality because the difference between its most likely (path value = 15) and least likely (path value = radio frequency module 300) is greater than the other example. • In step S800, the preamble detection method begins, and then in step S802, the baseband module 310 performs a Viterbi solution on the demodulated input data to obtain the final stage of the path value. Next, the preamble detection module 312 calculates a path value ratio of the maximum value to the minimum value of the last stage of the path value (S804), and compares the path value ratio with a predetermined ratio threshold stored in the register ( S806), if the path value ratio is smaller than the ratio threshold, step S808 is performed; otherwise, the process returns to step S802 to perform the next Viterbi decoding. Figure 9 shows a trellis diagram with 16 states of radix-4 in Viterbi decoding, showing all possible states of the encoded data in the time series. m — At each data time, the data can be one of the states 00 to 33. The Viterbi decoder calculates the likelihood of all input data in each state to generate a path value, represented by points 00 to 33 in Figure 9. The path value represents the likelihood of each candidate state for each possible previous state. If the probability of the maximum and minimum values in the path value is very similar, it means that the transmission quality is poor, and the decoded data may be wrong, so a possible error indication signal may be generated. The encoding can be Barker code, DBPSK, DQPSK, and CCK. The path value ratio can be corrected by the following formula 0758-A32772TW1 (20110525) ]9 I36220g 96137043 Patent Specification. July 8th, 00, revised replacement page Calculation:

Metric ratio = max ( Metric[z] ) / min ( Metric[z]) (1) where Metric[/] is the final state of the path value and max (Metric [z·]) is the maximum value of the final state of the path value And min (Metric[/]) is the minimum value of the final state of the path value. In step S808, since the path value ratio is smaller than the distance threshold value, the error count value error_count' is added because the maximum value and the minimum value are too close to each other. Identification is difficult, so the received constellation data may be destroyed. The pre-detection module 3 12 then checks if the error count value error_count exceeds the error threshold (S810), and if so, generates an error indication signal in step S812, and if not, returns to step S804 to perform more Viterbi decoding. The error threshold can be stored in the scratchpad. Both the path value threshold and the error threshold can be set by the control register at initialization. While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application.
